BUNCH


The BUNCH was the nickname for the group of mainframe computer competitors of IBM in the 1970s. The name is derived from the names of the five companies: Burroughs, UNIVAC, NCR, Control Data Corporation, and Honeywell. These companies were grouped together because the market share of IBM was much higher than all of its competitors put together.
During the 1960s, IBM and these five computer manufacturers, along with RCA and General Electric, had been known as "IBM and the Seven Dwarfs". The description of IBM's competitors changed after GE's 1970 sale of its computer business to Honeywell and RCA's 1971 sale of its computer business to Sperry, leaving only five "dwarves". The companies' initials thus lent themselves to a new acronym, BUNCH. International Data Corporation estimated in 1984 that BUNCH would receive less than $2 billion of an estimated $11.4 billion in mainframe computer sales that year, with IBM receiving most of the remainder. IBM so dominated the mainframe market that observers expected the BUNCH to merge or exit the industry. BUNCH followed IBM into the microcomputer market with their own PC compatibles. but unlike that company did not quickly adjust to retail sales of smaller computers.

Fate of BUNCH

;Burroughs & UNIVAC: In September 1986, after Burroughs purchased Sperry, the name of the company was changed to Unisys.
;NCR: In 1982, NCR became involved in open systems architecture, starting with the UNIX-powered TOWER 16/32, and placed more emphasis on computers smaller than mainframes. NCR was acquired by AT&T Corporation in 1991. A restructuring of AT&T in 1996 led to its re-establishment on 1 January 1997 as a separate company. In 1998, NCR sold its computer hardware manufacturing assets to Solectron and ceased to produce general-purpose computer systems.
;Control Data Corporation: Control Data Corporation is now Syntegra, a subsidiary of British company BT Group's BT Global Services.
;Honeywell: In 1991, Honeywell's computer division was sold to French computer company Groupe Bull.
